1. Pathogenic Organisms:
* Bacteria: Many bacteria are harmful, causing infections like E. coli, Salmonella, and Staphylococcus.
* Viruses: These tiny, infectious agents can cause diseases like influenza, HIV, and the common cold.
* Fungi: Some fungi, like Aspergillus and Cryptococcus, can cause respiratory and other infections.
* Parasites: Organisms like protozoa (e.g., Giardia) and helminths (e.g., tapeworms) can cause intestinal infections.
2. Organisms Requiring Specific Biohazard Precautions:
* Organisms classified as BSL-2 or higher: These organisms have the potential for serious or lethal disease. They require specific lab protocols and equipment for safe handling.
* Genetically Modified Organisms (GMOs): Some GMOs may pose unknown risks, and their release into the environment is strictly regulated.
3. Allergenic Organisms:
* Animal allergens: Some people are allergic to animal fur, dander, saliva, or other substances.
* Plant allergens: Pollen, nuts, latex, and other plant-derived substances can trigger allergic reactions.
General Precautions:
* Always wear appropriate personal protective equipment (PPE): This includes lab coats, gloves, safety glasses, and face masks.
* Follow all lab safety protocols: This includes proper waste disposal, sterilization techniques, and handwashing.
* Never eat or drink in the lab: This prevents accidental ingestion of harmful substances.
* Report any spills or accidents immediately: Safety is paramount in any lab setting.
Important Note: The specific organisms you should avoid will depend on the specific lab you are working in and the type of research being conducted. Always follow the instructions of your lab instructor and the laboratory safety protocols.
